LoRa is ideal for applications requiring long-range, low-power, and secure data transmission. + +1. Modulation Technique: LoRa uses Chirp Spread Spectrum (CSS) modulation, which spreads the signal across a wide frequency range, providing robust resistance to interference and signal degradation. +2. Long Range: LoRa can transmit data over distances up to 15 km in rural areas and 5 km in urban areas, making it suitable for a wide array of applications. +3. Low Power Consumption: Devices using LoRa can operate on small batteries for several years due to the low power requirements. +4. Low Data Rate: While LoRa supports long-range communication, it is optimized for low data rates, typically ranging from 0.3 kbps to 50 kbps. +5. Secure Communication: LoRa provides strong security features, including end-to-end encryption, ensuring data integrity and confidentiality. +6. LoRa is typically used in a star-of-stars topology where gateways relay messages between end-devices and a central network server. The gateway acts as a transparent bridge, converting RF packets to IP packets and vice versa. + + + +## Hardware Products + +
